ratus, of which the followingis a specifi cation. i a

My invention 1s adapted for the cont nuous compression of substancessuch as eot ton-seed, linseed, peanuts, and beans for extracting oiltherefrom in an effective and economical manner.

The details of construction, arrangement, and operation of the parts areas hereinafter described with reference to the accompanying drawing, inwhich i Figure 1 is a plan view of the extractor.

Fig. 2 is a longitudinal section of the same. I I

Fig. 3 is a' plan view of what may be termed a drain plate. i

l Fig.4 is a central section thereof.

Fig. 5 is an inner end view of the compression cylinder and adjunctiveparts.

Referring to Fig. 2, I provide a rotary compressor and conveyer 1, whichis cylindrical in cross section, but differential in diameter, one-half(1 of its length being larger than the other half (1), the interveningportion (1) being tapered, as'shown, and the larger portion (1 having aspiral groove 2, while the reduced or smaller portion (1) is smooth.

The spiral groove serves to receive and feed forward the oil-bearingmaterial as the compressor or conveyer is rotated.

Assembled or arranged closely one in con tact with the other, andforming a closure or chamber for the compressor 1, is a plurality ofwhat may be termed drip plates or elements 3 of washer-like outline,each having a central orifice or eye therethrough, the alining walls ofwhich orifices or eyes of said drip plates or washers forming the wallsof the chamber for the piston and conforming to the outline thereof,said walls being slightly spaced off from the reduced or smaller portionof said piston, as shown in Fig. 2, for the passage of the materialunder treatment. The series or plurality of washers or drain plates 3have each upon opposite sides thereof around its central orifice or eye4 an annular boss or thickened hub 5, the outer portions of the parts 3being narrower or thinner, and thus separated threaded sleeves from eachother by annular radial spaces 6.

Ducts or passages 7-see Fig. 4extend out through the hubs 5, and'servefor escape of the oil or other liquidexpressed from the substances beingtreated;

The series or plurality of washers or drain plates 3 are held solidlytogether in their positions by means of four stout rods or members 8passing through sleeves or bosses 9 upon amember 10 at one of theirends, and through similar sleeves or bosses 11 upon a tubular cap 12 attheir opposite ends, said rod ends having applied thereto and be ingheld firmly in place by means of screw or nuts 13 and 14, respectively." The thus assembled plurality of 'washers or drain plates arethemselves sandwiched between end members or plates 15 and 16, havingrecessed salient portions or extensions 17 and 18 respectively,conforming to the surface of and held between the rods 8.

Fitted within tapered recesses 19 and 20 of the members 15'and 16 is atapered member 21 in continuation of a chute 22 of a conveyer23, and aconical or tapered head or closure 24, respectively, the former fordelivering or feeding the required material, as aforesaid, to the spiralgrooved conveyer 1.

The part 24 has corner projections 25 serving as guides on the rods. Theclosure 24 has also a seat 26 to receive the compressor 1*.

Within the cylinder 12 is a cylinder 27 whiehis opened at its front end.This de-' vice is operated by Water pressure from pipe 30, and has anoutlet pipe 31. It will be understood that the cylinder 27 is alwaysunder pressure. The forward end of cylinder 27 enters a recess 29 in theback of part 21.

A conveyer 32 similar to conveyer 23, applied to the outlet end of thedevice as seen in Fig. 2, disposes of the by-products as the expressingor extracting action proceeds, as will be readily appreciated.

The spirally grooved feeding conveyer is suitably rotated or driven byintergeared pinions 33 and 34 upon the pinion shaft 33*, and a beltdriven, pulley 35 on the shaft 36 of the pinion 34, or it may beotherwise rotated 'or driven.

The device, as an entirety, together with the shafts of the describedgearing, issupported upon a suitable framework 37 and leg member 38,respectively.

It is observed that the material to be treated, the character of whichis above indicated, enters, troin the conveyer 23, the chute 22 and isdelivered to the compressor 1, whence the material is carried or thrustiqrwardly ,the latter, it being fed there; from or forced by the taperedportion 1 of the compressor withthe surrounding space a exerted .uponthefcone or closure valve 24 by the cylinder to allow of the escape ofthe .by-products ifrom the compressor surroundchamber through thepassageway as the resultiof the removal of said closurevalve or coneaway a from its seat, and the discharge of said byproducts into theconveyer 32: effecting their removal or other purpose. It is noted inthis connection that, avhen the material has vceased feeding, or,rather, there being none for feeding, the ivalveflor :closure 24 will beautomatically closed under pressure from the cylinder 27.

-Ha-ving thus described my invention, what I claim as new and desire tosecure by Letters Patent is: a

"1. A press for the purpose specified comprising aspirally groovedcompresor which --=is.cyl;indrical in cross section, a .body surroundingsaid compressor which is formed of a series of plates having thickenedhub portions and reduced or thinner outer portions, the hubs havingducts leading outward from the compressor into the space between theouter portions of the plates, as described.

2. In a press of the character described, the combination of acompressor formed of two lengthwise cylindrical portions difiering indiameter, and an intermediate tapering portion by which they areconnected,

the larger and tapered portions having a spiral feed groove, a bodysurrounding said compressor and formed of a series of plates arrangedparallel, central or :hub portions being provided with ducts leadingoutward and their outer portions being thinner than the hub portions andthus separated by narrow spaces, the smooth surfaces of the re- ..ducedportion of the compressor being separated from the surrounding body by anarrow annular space, and means for rotating the conveyer, as described.

,3. The combination with a spirally grooved compressor, and asurrounding body formed of a series of plates, lateral passages forescape of liquid, the end plate 18 having a conical recess, and aconical closure 24 adapted to fit in said recess, and a hydraulicallyoperated piston whose inner end is seated in said conical closure, asdescribed.
